StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 7 July 2026; the live site may have changed since.

Castmates: Offline AI Roleplay has the basics covered well, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing several security headers.

Launched on Product Hunt on July 7, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 6 days before launch. Our crawler found 11 technologies on this site, covering seo, analytics, CDN, and CSS frameworks. The stack includes Astro, Tailwind CSS, and Apple App Store.

It's also running the same core stack as 119 other launches.
